Diagnostic Considerations

The roentgenologic appearance of pulmonary interstitial emphysema (PIE) can be confused with the following [26] :

  • Air bronchograms in respiratory distress syndrome (RDS)
  • Aspiration pneumonia
  • Pulmonary edema
  • Distended airways in patients on mechanical ventilatory support

Other differential diagnosis of persistent pulmonary interstitial emphysema includes the following:

  • Congenital cystic adenomatoid malformation
  • Lymphangiectasia
  • Bronchogenic cysts
  • Congenital lobar emphysema
  • Cystic lymphangioma
  • Sequelae of a prior infection
  • Diaphragmatic hernia
